This week AT&T unveiled a phone line of messaging and touch screen phones from Pantech and Samsung, and the carrier announced that these would arrive in time for the winter holidays. Two of these new feature handsets were from Pantech, and two additional phones will arrive from Samsung. Pricing has yet to be announced, but AT&T did share some key details on these upcoming handsets.

Pantech Reveal will be revealed to all on October 18, and this slim slider phone will feature an open-faced numeric keypad, which slides to reveal a full QWERTY keyboard. This handset is designed for users looking to text, IM or e-mail colleagues and friends. It utilizes the AT&T Navigator technology and offers GPS support. This sleek slider will be available in red and blue when it arrives later this month.

Pantech Impact could make quite an impact (yes, the puns continue) later this fall. This feature phone is probably not meant for hardcore business users – it is available in pink and blue – but if you’re looking for a handset that has a bit of flare this might be the one. It offers an OLED screen to let users send text messages and make calls. It is a sideways flipper that reveals a second display screen and full physical keyboard for those times when you need to do some serious texting or messaging.

Samsung Mythic will arrive in November as a touchscreen-only device, powered by Samsung’s own TouchWiz user interface. It will be compatible with AT&T Mobile TV, and features a 3.3-inch touch screen for use with AT&T Navigator, AT&T Social Net and other apps.

Samsung Flight takes off in November, and this vertical slider phone offers a full reveal keyboard. But it is also designed to allow one-hand texting, and offers on-touch access to key functions such as shortcuts and favorites. This feature handset will be available in red and silver.

All of these handsets will support AT&T’s new att.net mobile browser, which will provider users with three windows to the Web. This will include a homepage, where users can access the global Internet, and assign bookmarks and shortcuts to favorite content. A second window will provide users with location-aware local news and weather, access to nearby locations such as places to eat and even ATMS, as well as driving directions and traffic updates. And a third window will provide news, sports and entertainment headlines.

Behold the New Android Phone from Samsung Mobile and T-Mobile USA
This week Samsung and T-Mobile announced the upcoming Behold II, a new handset powered by Google Android. This handset features a full-screen that integrates the open Android platform with Samsung’s TouchWiz user interface, and runs on T-Mobile’s high-speed 3G network. The Behold II will be available by end of the year (pricing was not announced).

3M Develops 3D Optical Film for Third Screen
Viewing video on a mobile device, including handsets and smartphones might just get richer. This week, 3M announced that it has developed a new, field sequential 3D optical film for mobile and handheld devices. This in itself isn’t that big a deal, but what makes this special is that this true auto stereoscopic 3D viewing could be done without the need to wear special glasses.
